sharding jdbc(二) 分库分表

 基于SpringBoot+Mybaits+sharding jdbc

 

由于sharding-jdbc是不支持动态进行建库的SQL，那么就需要一次把需要的数据库和数据表都建好

 

数据库脚本：

SET FOREIGN_KEY_CHECKS=0;

-- ----------------------------
-- Table structure for t_order_0
-- ----------------------------
DROP TABLE IF EXISTS `t_order_0`;
CREATE TABLE `t_order_0` (
  `id` BIGINT(20) NOT NULL AUTO_INCREMENT COMMENT '主键id',
  `order_id` VARCHAR(32) DEFAULT NULL COMMENT '顺序编号',
  `user_id` VARCHAR(32) DEFAULT NULL COMMENT '用户编号',
  `userName` VARCHAR(32) DEFAULT NULL COMMENT '用户名',
  `passWord` VARCHAR(32) DEFAULT NULL COMMENT '密码',
  `nick_name` VARCHAR(32) DEFAULT NULL,
  PRIMARY KEY (`id`)
) ENGINE=INNODB  DEFAULT CHARSET=utf8;

-- ----------------------------
-- Table structure for t_order_1
-- ----------------------------
DROP TABLE IF EXISTS `t_order_1`;
CREATE TABLE `t_order_1` (
  `id` BIGINT(20) NOT NULL AUTO_INCREMENT COMMENT '主键id',
  `order_id` VARCHAR(32) DEFAULT NULL COMMENT '顺序编号',
  `user_id` VARCHAR(32) DEFAULT NULL COMMENT '用户编号',
  `userName` VARCHAR(32) DEFAULT NULL COMMENT '用户名',
  `passWord` VARCHAR(32) DEFAULT NULL COMMENT '密码',
  `nick_name` VARCHAR(32) DEFAULT NULL,
  PRIMARY KEY (`id`)
) ENGINE=INNODB  DEFAULT CHARSET=utf8;
